ANALYTICAL  CHEMISTRY. 
The  examination  in  this  branch  consisted  in  the  analysis  of  a  mixture  of 
from  three  to  five  salts  or  compounds  in  the  form  of  powder.  Each  student 
was  given  two  hours  in  which  to  carry  out  this  work. 
MICROSCOPY. 
Make  a  sufficient  number  of  sections,  transverse,  longitudinal-radial  and  lon- 
gitudinal-tangential, of  the  specimen  given  you  for  study,  and  use  such  clear- 
ing agents,  test  solutions  and  stains  as  are  necessary  to  determine  the  following 
points  : 
(1)  Is  the  specimen  derived  from  the  pteridophyta,  from  the  gymnosperms, 
from  the  monocotyls  or  from  the  dicotyls  ?  (2)  Is  it  from  a  root,  from  a  stem 
or  from  a  petiole?  (3)  Is  it  monostelic,  polystelic  or  schizostelic  ?  (4)  To 
which  of  the  following  varieties  do  its  vasal  bundles  belong  :•  Closed  collateral, 
open  collateral,  bi  collateral,  concentric  with  a  central  xylem,  concentric  with 
a  central  phloem,  or  phloem  and  xylem  bundles  distinct?  (5)  Make  a  dia- 
gram (not  a  detailed  drawing)  of  the  cross-section  on  a  sufficient  scale,  and 
point  out  such  of  the  following  parts  as  are  present :  The  xylem  of  a  bundle, 
the  phloem  of  a  bundle,  the  pith,  the  epidermis,  the  periderm,  a  medullary 
ray,  the  endodermis  and  the  pericycle.  (6)  Indicate  which  of  the  following 
tissues  are  present :  Collenchyma,  stone  cells,  bast  fibres,  ducts,  tracheids, 
complex  laticiferous  tissue,  simple  laticiferous  tissue,  crystal  cells,  resin  cells. 
(7)  In  case  ducts  occur,  name  the  different  varieties  present.  (8)  If  crystals 
are  present,  what  is  their  composition  ?  (9)  Is  starch  present  in  the  speci- 
men, and  by  what  means  do  you  determine?  (10)  Is  tannin  present ?  If  so, 
is  it  more  abundant  in  the  parenchymatous  or  in  the  prosenchymatous 
tissues?  (11)  What  test  did  you  apply  to  determine  the  presence  or  absence 
of  tannin  ?    (12)  Judging  by  the  structure,  is  the  specimen  from  an  aquatic
